ProjectTransmission Lightning Arrester Application Study

Located: Connecticut, Massachusetts, and New Hampshire

The Transmission Lightning Arrester Application Study project was an investigation into line outages caused by lightning events on certain transmission lines. The Utility requested a review of the lightning related outages to determine if the frequency of these outages is outside the norm and if design modifications may be able to improve the performance of those lines. RLC was responsible for investigating the causes and made recommendations on potential mitigation options based on our field inspections. The intent of this investigation was to determine the most feasible mitigation alternative to reduce the number of outages caused by lightning.

Scope of Services:

Reviewed the Utilities’ records for outage rates per year caused by lightning events.
